To ensure that our operation is environmentally responsible

In accordance with environmental legislation, our management, with its sustainability approach, means that we perform our activities in line with our Corporate and Environmental Policy. Environmental studies and procedures were carried out during 2019, as well as environmental controls and offsetting, the total investment for which was COP 10,031 million. 

Institutional management

With a view to reinforcing our environmental management, we carried out such actions as the following. 

All companies measured and certified their carbon footprint in accordance with ISO 14064 standard, and our affiliate GdO took part in the Valle Carbon Neutral program (CVC and DAGMA).  

Transmetano was party to the Production and Sustainable Consumption agreement (Proaburrá Norte, CEO and Prosur) for verifying its carbon footprint. It also supported the Sustainable Mobility program in Medellín, which runs from 2017 to 2022.  

The ANDI Biodiversity and Development in the Caribbean agreement, to which Promigas and SPEC are party, continued.

At a pig farm at the Villa Don Bosco Training Center in Santander de Quilichao, GdO began a pilot program to generate biogas from porcinaza. This process, which closes energy cycles, is a successful example of the circular economy. Don Bosco is a training center in technical skills for young people from towns and villages where the social risk is high.​

Adaptation to climate change

To accompany the company’s operations and processes with initiatives which generate environmental value, and to evaluate the current and potential environmental impacts of our entire operation in terms of climate change. 

Natural gas is currently one of the principal and most relevant sources of energy used by human beings for both domestic and industrial purposes, since it plays an important role in promoting a low-carbon economy.

However, although it is a cleaner source of energy than others, such as petroleum, we should continue our work to ensure that we can deal with risks relating to climate phenomena, mitigate our impacts, improve our infrastructure and strengthen our ability to react, not only in order to reduce costs involved in unscheduled maintenance and losses resulting from disasters but also to provide our interest groups with an ever more diversified portfolio with offers of renewable and decarbonized services. 

The company’s environmental management seeks not only to evaluate and reduce current and potential risks in its entire operation by reducing, mitigating and offsetting the carbon footprint but also to accompany processes that add value to the business and for our interest groups.

​​ Improving energy efficiency and reducing greenhouse gas emissions are key aspects of our management and are the reason why we have annual and medium-term emission reduction targets and a strategy for offsetting emissions.

With a view to administering our carbon footprint and reducing our emissions, we have performed the following actions. 

Contracting audits of emissions generated throughout the organization, with 100% coverage.

CEO carried out a project to plant 7,047 trees, with their respective isolation, as a contribution to the capturing of greenhouse gases and the conservation of natural resources (water, soil and air). The project was carried out in six municipalities in Cauca province: Caloto, Caldono, Corinto, El Tambo, Morales and Suárez. Various parties were involved: community, education establishments, local councils, the environmental authority (CRC).

Reduction in greenhouse gas emissions

Our affiliate Transmetano has been developing a forestry plantation of Pinus oocarpa (126 hectares, 138,830 species) in Yolombó (Antioquia) since 2009, in order to capture carbon from this plantation to offset company emissions, and as at a 2015 cut-off date (South Pole Group, 2017) this had generated 15,975.9 tonnes of equivalent CO2 as the average carbon content stored by the plantation, which offsets 100% of the CO2 and CH4 emissions generated by Transmetano.

Caring for biodiversity​

We are committed to minimizing and controlling impacts caused as we carry out our operations, and we consider conserving biodiversity a criterion from the earliest project planning and design stages.

Our approach is based on knowing and preventing environmental risks to biodiversity and minimizing and controlling impacts as we carry out our operations, considering the conservation of biodiversity a criterion from early stages. Right from the design stage we conduct field studies in order to prevent or reduce to a minimum the effects of our network passing through ecosystems or settlements with a high biodiversity value. 

We have a Corporate Policy and an Environmental Policy which include a commitment to biodiversity, and we perform our activities accordingly, by minimizing impacts. ​

Conscious of the need to contribute to preserving tropical dry forest, we directed our biodiversity conservation efforts in 2019 at this important ecosystem. The offsetting plans presented include forming natural reserves for civil society, a protected area category of around 400 hectares including conservation projects and production projects, and the purchase by Promigas and SPEC of around 1,000 hectares of land in nature reserve zones for sanitation. 

At the same time, through the Biodiversity and Development initiative, we took part in study groups and work sessions to review the best conservation practices engaged in by companies and other organizations. As a result of this, we were recognized by ANDI for our commitment to preserving tropical dry forest. 
Promigas built approximately 194 km of new gas pipeline after proposing a construction strategy that involved a 20% reduction in authorized area, which resulted in fewer trees being affected. Routes that were selected were outside any area that was classified in a protected category, although in 2019 Atlántico Regional Autonomous Corporation declared one zone an integrated regional management district (DRMI), which implies that it comes into the protected area category, and 0.6% of the route of one of the new projects was inside the DRMI. This forced us to establish additional measures with the authorities for reducing areas intervened and to provide wildlife corridors so as not to interrupt routes taken by the protected cotton-top tamarin, with weekly follow-up monitoring of this species.  

We trained our suppliers to frighten off and rescue wildlife while building or maintaining gas pipelines and to deal with wasps and bees when carrying out pruning and felling activities and maintaining infrastructure (electricity networks, structures).  

Meanwhile, our affiliate GdO, as part of the BanCO2 strategy, has been supporting three families who have been protecting 13 hectares since 2017. The target was to increase the number of hectares protected in 2019 to 374.75, which was achieved with a 102% compliance figure, namely with 383 hectares and 13 families. This project was presented in Valle del Cauca at the National Bicycle Forum, and through this the service for studying biodiversity in four municipalities has been administered, to identify species that are registered in the Red Book of Endangered Species in Colombia and inhabit areas that are currently protected. 

In 2019, Promigas carried out the following recovery and offsetting activities. 

15,165 trees were planted on public and private property,  in conjunction with the environmental authorities.

650 epiphytes were rescued and transferred to a 50-hectare area in El Tamarín Nature Reserve in the settlement of Arroyo de Piedra, which comes under the city of Cartagena. 

Progress was made on the following, under the ANDI agreement.

The National Parks   organization was asked to create 400 hectares in Civil Society Nature Reserves (RNSC), including conservation agreements signed by communities. 

The design of a fauna or flora species protection program, for native species or ones in an endangered category, with conservation and restoration actions aimed at Caribbean connectivity.

Support for the scheme to implement  the update of Serranía de Coraza Protective Forestry Reserve Management Plan.  


Implementation of conservation agreements covering  an area of 328.5 hectares with communities in tropical dry forest ecosystem areas in the SFF Los Colorados - SFF Corchal corridor.​

Administration of ANLA approval for offsetting SFF Los Colorados property through 120 hectares corresponding to the San Mateo Loop project (approved by means of Resolution 1115 of 2019), 55 hectares corresponding to the Mamonal - Paiva project (approved by means of Ruling 8383 of 2019), and 148 hectares to the Sociedad Portuaria El Cayao (SPEC) project.

Drawing-up of biodiversity inventories during implementation of RNSC management plans in prioritized bodies of water and priority zones for Caribbean connectivity that will be used as a basis for monitoring in 2021 and 2023

The route followed by our gas transportation system crosses certain protected areas, on land belonging either to the state or to private individuals. The operation itself and maintenance activities are carried out in these areas, in line with directives issued by the environmental authorities. Many of these gas pipelines were acquired from other companies.

Owned, rented or administered operations centers located in or next to protected areas or zones of great biodiversity value outside these areas  

Resources and waste management

To promote the efficient uses of resources, in order to prevent and minimize environmental impacts of the company’s operations.  

The organization seeks to minimize environmental impacts and risks and to strictly adhere to laws governing the matter. 

The operations of Promigas and its companies aim to improve the overall management of resources such as water, energy and waste by promoting the prevention of waste generation, fostering reuse and recycling, and favoring the tracking thereof. We have also introduced a system of management, storage and delivery to authorized handlers of dangerous and non-dangerous waste, in order to guarantee that this is correctly treated.

As far as resources like water and energy are concerned, we control consumption associated with our processes, foster the use of other renewable energies, and have various measures aimed at reducing consumption. ​


Environmental compliance​

Notification was received in 2019 of a fine of COP 165,448,306 imposed by ANLA
for failing in 2008 to carry out an environmental procedure with the national authority,
the Ministry of Environment and Sustainable Development, for carrying out an “urgent” work
for which the local authority had granted permits, a situation that was not accepted by ANLA.
The preventive actions taken include carrying out the environmental procedure in order to
ensure that all projects fully meet legal environmental requirements, even in cases
​where works are required as a matter of urgency. ​
